What Is Click-Through Rate (CTR)?

Definition

The ratio of users who click on a specific link to the total number of users who view a page, email, or advertisement.

Why It Matters

CTR measures genuine engagement — clicking requires active intent, unlike passive impressions or opens. Whether in email, paid ads, or organic search, a low CTR signals your message is not resonating with your audience, even when visibility is high.

How It Works

CTR is calculated as (Clicks ÷ Impressions) × 100. In email, it measures how many recipients clicked a link. In Google Ads, it measures how many people who saw the ad clicked it. In organic search, Google Search Console shows CTR per query — and combining average position with CTR reveals whether your title tags and meta descriptions are compelling enough to earn clicks.

Real-World Example

A gym equipment retailer's Google Ads campaign has a 0.8% CTR. After rewriting ad copy to lead with "Free 2-Day Shipping + 30-Day Returns" instead of product names alone, CTR rises to 3.1% — significantly reducing cost per conversion without any bid changes.
